• 400 tie points total: 300 tie-point IC-circuit area plus two 50 tie-point distribution strips providing 4 power rails.
• ABS plastic body with black printed legend. Color legend on distribution strips.
• Contacts are Phosphor Bronze with Plated Nickel Finish, rated for 50,000 insertions.
• Rated at 36 Volts, 2 Amps.
• Insertion Wire Size is 21 to 26 AWG, 0.016 to 0.028 inches diameter (0.4 to 0.7mm diameter)
• Peelable adhesive tape backing provided for attaching to a surface.
• Size: 3.3 x 2.1 x 0.3in (84 x 54.3 x 8.5mm).

• Provides 4.5 Volt power from 3 AA cells (not included).
• Smooth machined male pins designed for breadboard use.
• Great for use with solderless breadboards (such as the BB830 and BB400).

BreadBoard-400 is a solderless (plug-in) breadboard with 400 connection tie-points (i.e. 400 wire insertion holes). It has 4 power rails. Solderless breadboards are great for building and testing new circuits because parts can be easily inserted and removed. They are completely re-usable. The BB400 has a 300 tie-point IC-circuit area plus four 25 tie-point power rails. The housing is made of white ABS plastic, with a printed legend giving numbers and letters for columns and rows. The internal contacts are phosphor bronze with a plated nickel finish. A peelable adhesive tape backing is provided for attaching it to a surface. BPS BreadBoards are Lead-Free and RoHS Compliant. Finished projects can be moved to a SB400 or SB404 Solderable PC BreadBoard to make them permanent.

The PW-3AA battery box has breadboard pins designed to plug into your breadboard. The machined male breadboard pins with strain relief heatshrink tubing provide a reliable long-lasting connection (as opposed to tinned wires that fatigue and break).

The battery box holds 3 AA batteries to provide 4.5 Volt power for your projects. A built-in slideswitch turns power on and off.

The battery box is best for circuits that don’t need an exact supply voltage. The voltage will go down from 4.5 Volts to 2.4 Volts as the batteries drain. For example, transistor circuits often work over a wide voltage range, and some integrated circuits accept a wide 3.3V to 5V supply voltage. If your circuit needs exactly 3.3 Volts, you will need to add a LDO (low dropout regulator). If your circuit needs 5 Volts, you need more AA batteries and a 5V regulator.
